Its a nice mist/fog shot. Nicely composed, bank on a third.
The tips of the mills sails are there, just barely, - perhaps slightly obscured by the mist. I would leave just a little more space at the top to make them more visible, or try to make them more visible.
Ive done this in the mod I uploaded.
As you know, the mist will give a very low contrast shot, as dark or black tones will be grey. So, you can leave as-is, or bring back a small amount of contrast, while retaining the mist, to give the buildings more definition, as done in the mod.

This just needs a small clockwise rotation - see my mod. The verticals of the cottage and barn are the obvious ones to check here, as well as the river bank.
However a receding river bank can sometimes give the impression of an image not being level even when it is.
It's always a close call in misty conditions as to how far you bring back the blacks from grey. Easy when there is some foreground detail as that will be less affected by the greyness of the mist so the brain accepts darker blacks there.
Less so when you have a scene such as this, but it is worth making the darker tones darker using Levels to get a broader range of tones in the image. A little extra contrast and darker tones improve the visual experience.
